Ultrahuman Ring AIR — Sleep, Recovery & Performance, On Your Finger

The Smart Ring That Earns Its Keep

The Ultrahuman Ring AIR is the lightest, most comfortable way to actually understand what your body is doing. Sleep, recovery, stress, training load — tracked 24/7 from a 2.4 gram titanium ring you'll forget you're wearing. No wristband. No subscription. No nonsense.

What It Tracks

• Sleep that actually means something: Deep, REM and light stages, sleep debt, restfulness — broken down so you can do something with it, not just stare at a graph.
• Dynamic Recovery Score: Blends HRV, resting heart rate, skin temperature, sleep quality and stress to tell you whether today's a green light or a back-off day.
• Stress & resilience: HRV-based stress tracking and circadian rhythm alignment so you can train, work and recover in sync with your body, not against it.
• Movement & metabolism: Steps, activity, calorie burn and metabolic insights — built around the science of how your body actually uses energy.
• Women's health, properly: Cycle phase tracking, ovulation prediction and pregnancy insights aligned to trimesters. Included, not paywalled.

Built to Disappear

Aerospace-grade titanium, tungsten carbide coating, 2.8 mm thin and just 2.4 to 3.6 grams depending on size. Water resistant to 100 metres so you can wear it surfing, swimming or in the shower. Battery runs 4 to 6 days on a charge, and a top-up takes about two hours. Charge it Sunday morning over coffee, forget about it until Friday.

No Subscription. No Catch.

Unlike Oura, the Ring AIR doesn't lock the good stuff behind a monthly fee. Buy it once, get the full feature set. Optional PowerPlugs are available if you want to go deeper — AFib detection, advanced cycle tracking, Brain Waste Clearance insights for cognitive recovery — but the core experience is all yours from day one.

Built for the Australian Way of Life

Whether you're chasing PBs on the bike, working shift, raising kids on broken sleep, or just trying to figure out why some days feel harder than others — the Ring AIR gives you the data and the context to do something about it. Tough enough for an ocean swim at Burleigh. Discreet enough for a boardroom on Collins Street. Light enough you'll forget it's on.
